Science Experiment: What is Pollution?

It is never to early to teach kids about pollution and the importance of taking care of our planet. In this experiment, we use vinegar as the “pollution” and watch how the “pollution” affects flowers. This science experiment is very easy and fun for all ages.


  1. Three small glasses or cups
  2. Vinegar
  3. Water
  4. Three flowers


  1. Fill the first glass with water; the second glass 3/4 water and 1/4 vinegar; and, the third glass 1/2 water and 1/2 vinegar.
  2. Place one flower in each glass.
  3. Wait up tp 24 hours and observe the changes with each flower.


Pollution is anything that makes our earth dirty and unhealthy. Land, air and water can all be affected by pollution. In this science experiment, the flower in the first glass should not change. The flower in the second glass should slightly wilt and the stem should turn beige. The flower in the third glass should be wilted and even more beige that that in the second glass. The more vinegar (pollution) in the water, the more changes seen in the flower.
